Container virtualization security.

As the threats are the same the counter measures i e. Learn about a strategy for scaling container security across organizations of any size. Container virtualization often referred as operating system virtualization is more than just a different kind of hypervisor. Os level virtualization is an operating system paradigm in which the kernel allows the existence of multiple isolated user space instances.

Application containers by contrast have different properties some of which bolster security and depending on usage some that can undermine it. In fact according to a forrestor research study 53 of enterprises deploying containers cite security as top concern. Containerization also called container based virtualization and application containerization is an os level virtualization method for deploying and running distributed applications without launching an entire vm for each application. Security functions that counters the threats are also the same for the aforementioned virtualized systems.

Containers use the host operating system as their base and not the hypervisor. A key property of containers is a more porous segmentation boundary relative to os virtualization. If we traverse the current market scenario it becomes clear that container based virtualization is rapidly gaining momentum across large scale enterprises as well as smes. Today security is much more of a concern with containers than it is with virtual machines.

Rather than virtualizing the hardware which requires full virtualized operating system images for each guest containers virtualize the. Finally security software and rules implemented at the container engine level can apply to all of its containers. Instead multiple isolated systems called containers. In the same line one must bear in mind that the security of the server hosting the containers is equally important as that of the container itself.

What does a more porous segmentation boundary entail. Cons of virtualization via containers. The threats highlighted in niap base virtualization protection profile apply equally to containers virtualized storage and sdn. Although there are many advantages to moving to virtualization via containers architects must address challenges and associated risks in the following six areas.

This is likely due to the fact that vm s have reached maturity in their deployment and the attack surfaces are fairly well understood.
